Construction arrangement of an elevator and method

A construction arrangement of an elevator, comprising a hoistway formed in a building, the hoistway comprising at least one hoistway opening leading in horizontal direction out from the hoistway, the opening being delimited by a lower edge structure and an upper edge structure;

• and
• a load in the hoistway lower than said opening;
• and
• a hoisting arrangement for hoisting said load, wherein said hoisting arrangement comprises
• a support structure mounted higher than said load;
• and
• a hoisting device;
• and
• at least one flexible tension member connected or at least connectable to said load;
• wherein the at least one flexible tension member is movable with said hoisting device in particular for thereby transmitting a hoisting force to said load to be hoisted, wherein said support structure comprises
• an anchoring beam structure comprising
• a lower end engaging the lower edge structure, in particular a face thereof,
• an upper end engaging the upper edge structure, in particular a face thereof, and
• a pivotal beam mounted to the lower end of the anchoring beam structure, the pivotal beam forming an obtuse angle from a horizontal face of the lower edge structure facing the hoistway and being configured to pivot in a first pivoting direction around the lower end of the anchoring beam structure towards hoistway in an operating position;
• and
• a support beam structure connected to the anchoring beam structure and protruding from the anchoring beam structure into the hoistway;
• and
• wherein said at least one flexible tension member hangs in the hoistway supported by the support beam structure.
